noob question Hey guys, i recently bought a '02 SS 
and i noticed it has an SLP MAF installed on it 
. I've heard that this is kind of a foolish mod as the maf isn't restrictive before 600 hp or sumpthin. That AND you need to tune for it. So far i've just left it on and hoped that the car had been tuned for it, cuz i don't see how i have any way of knowing. But the other day my battery died 
and i'm wondering if this causes the car to lose any tuning that'd been done to it.
I've been told disconnecting the battery will force the computer to re-learn whats best for it and is good after certain mods. Help me out fellas, i'm kinda lost.

If you look in the SLP MAF you'll notice a little resistor soldered in... they put this in so that it *should* work pretty well w/the stock tuning (assuming you mean an SLP Z06 MAF) ... Still isn't perfect... but better than running a Delphi Z06 MAF w/out any tuning
Regarding losing the tune... nope... it's probably not tuned for it, probably the resistor doing it... but the "tune" in the PCM isn't erased by lack of power, only way to erase it is w/a Tech 2 or some tuner software
When you disconnect the battery, the PCM relearns the fuel trims and spark learn (to determine if you can get full timing w/out knock) as well as clearing any SES codes... it also resets the readiness tests , but will have no ill effect... it will relearn w/driving
